如何定量测算“股债跷跷板”的影响

Summary of Key Points from Conference Call Industry or Company Involved - The discussion revolves around the relationship between the equity market, specifically the 中证 500 Index, and the bond market, particularly the 10-year government bond yield. Core Insights and Arguments - There exists a "seesaw effect" between the stock market and the bond market, where the 中证 500 Index and the 10-year government bond yield are positively correlated. Specifically, for every 100-point increase in the 中证 500 Index, the 10-year bond yield rises by approximately 0.9 basis points [1][2][5]. - The Bernanke three-factor model effectively decomposes the yield of the 10-year government bond, achieving an R-squared value of 0.85 when fitted to data since 2016. This model uses the 7-day reverse repo rate as a proxy for short-term rates, current CPI for inflation expectations, and the difference between social financing and M2 to represent economic conditions [1][4][7]. - The relationship between the 中证 500 Index and the 10-year bond yield shows a leading effect, indicating that an increase in the stock index can lead to a rise in bond yields in the following month [2][11]. - The bond market has already absorbed the impact of the recent rise in the equity market, with an increase of about 4-5 basis points in the bond yield since mid-June [14]. - If the equity market rises by an additional 5%, it could exert an extra pressure of about 3 basis points on the bond market, pushing yields to a range of 1.70% to 1.75%. A further 10% increase in the equity market could raise yields by approximately 6 basis points, resulting in a range of 1.75% to 1.80% [2][14]. Other Important but Possibly Overlooked Content - Different equity indices have varying degrees of influence on the 10-year bond yield. The 中证 1,000 and 中证 2000 indices show weaker correlation with the bond market compared to larger indices like the 上证综指 and 深证成指 [8][9]. - The structural integrity of the model is affected by the inclusion of large-cap indices, which can disrupt the original model's structure, particularly the impact of social financing minus M2 [9]. - The current market environment has led to a notable increase in the correlation between the 中证 500 Index and the 10-year bond yield, a phenomenon not seen in the past decade. This is attributed to stable fundamental and monetary conditions [15].
